Matching one layer object color with another layer object color in QGIS

I’m kind of very beginner in QGIS. I have made one layer of "cells" and visualised them on map with different colors representing cell numbers like this:

The idea is that this layer is like database of the network which is always loaded in my QGIS project and sometimes I need to add some data from these cells on the map, which is loaded in another txt file(s).

I would like the points of this data to represent the same color which is stored in another layer(network database layer). Is there any way how to match these colors?

For example here below you can see the image of the 2 layers loaded together and I added labels to the points. For example how can make points with attribute number 280 to be orange or number 281 to be green?
